Abstract: This invention provides a camera system installed on the front end of a vehicle, either on the left front, the right front, or both sides, that prevents accidents resulting from the driver's propensity to protrude into oncoming traffic to view that traffic. The camera is linked via wired or wireless connection to an onboard computer and a commercially available navigation display that is placed within the passenger compartment of the vehicle. The driver reviews a visual description on the display of any oncoming traffic in the form of motor vehicles, pedestrians, cyclists, animals and the like on the navigation display via a single screen, split screen or alternating screens. The camera system is furnished with a speed sensor that detects when the vehicle reaches a threshold speed of 3 miles per hour to activate or de-activate the camera. This camera system can be retrofitted into older vehicles.
